Alittle help please

Hi there!

can anyone help me or point me in the right direction,

i am trying to code a calculator that will except floating point numbers upto 6 digits, including the decimal point...

would i need a string to check each of the numbers to make sure the dont go over 6 digit limit??


Thanks in advance

Well both the scanf functions and cin have support for doing precision. But you could preprocess a string if you really wanted to.

[edit]
Alittle help please as a title is bad form, btw. Many people disreguard questions with this title.

all i know is use double for floating point #

like this:

void main()
{
double n1, n2, n3
}
then just program them in.

try something like

if(n1 = > 6)

hope it helps

You need to use a string to read the number, then convert it to a double when you've checked it for length.

A little help please isn't a good name i suggest some random marks like this $&^%$%(&%$^#$$^&*%(^%^(&%

Keep multiplying the number * 10 until there is no decimal point

Code:

---

while(int(num)!=num)
{
  num*=10;
}

---

Then if this number divided by one million is less than zero then the original is 6 digits or less else it isn't.

PS. I *think* this works but I haven't tested it! :D

void main() is wrong, please don't promote its use.

just add the word baloonies

I usually use float main().

what do you use it for?:confused:

>what do you use it for?
i usually use it when i want to brush up on my bad programming habbits. void main() also helps with those.

how does that cure habits?????????:confused:


--shish--:rolleyes:

void main() curing habits :rolleyes:
